Abstract (en)
[origin: EP3511588A1] A sealed bearing is provided of which the seal torque is small, and of which the temperature is less likely to rise excessively. The sealed bearing includes an inner race (2); and seal members (7) each including a seal lip (10) made of rubber. Each seal lip (10) includes a plurality of protrusions (15) circumferentially spaced apart from each other, and kept in sliding contact with the inner race (2) with fluid lubrication condition generated between the protrusions (15) and the inner race (2). Each protrusion (15) has a circular arc-shaped cross section along the circumferential direction, and the circular arc-shaped cross section has a radius (R) of 0.4 mm or more and less than 9.0 mm.
